Lo and behold one of the boot options was Windows Boot Manager. I didn't manage to stop the boot attempt and I got a black screen with a blinking cursor in the top left - again curious and excited I restarted and went into the BIOS. Exited Windows setup, restarted the system

This time however I got another copy of Windows 10 on a new USB drive, started the Windows setup, clicked through the available partitions to install, yet did not take any action. Let the system try and boot any ways and this time got the message 'No operating system found' immediately followed by 'Select proper boot device' error.Ĭurious and excited, I decided to run through some more command line stuff with Diskpart to once again repair the EFI partition. Put the original boot SSD back in place of the new HDD, and it showed in the BIOS - though still no boot/windows boot manager. Took out the other drives and stuck the HDD into the first Intel 6gb sata slot.

Never the less, hoping it was a software issue, I decide to try a new Windows install on a spare HDD. Others had reported this on these Asus boards and the weird behavior of one of my SSDs and HDDs (disappearing at random or when stressed under load as well as causing Windows login to freeze) seemed to be related. It was probably happening all the while I have been having this issue.Īfter reading around yet some more, I started to come to the realization that it most likely a motherboard issue, specifically a dying SATA controller. Turned the system on this morning, and for the first time noticed that the Boot Device led on the motherboard was lit(red). I also had backed up the original EFI data, and subsequently replaced it as a final test. And I did rebuild the two partitions, which succeeded yet did not resolve the issue. If it was EFI partition related, the system wasn't confirming either way. Using the old MBR commands(in hopes it would force the Windows startup repair to recognize and fix a problem).Removing CMOS battery and replacing with a new one - my HDD started showing up again after doing this.bcdboot c:\Windows /l en-us /s vz /f ALL.sel vol 1 (note that Diskpart states EFI partition is 'hidden').Next I tried to repair the EFI with Diskpart in the shell: It said it was not able to fix any problems. dev/sda4-ntfs-/media/sda4-450.00MiB-327.71MiB-122.29MiB-hidden,diagĪs I am able to boot Windows installation from USB, I tried the standard startup repair. dev/sda2 (exclamation mark) Microsoft reserved partition-unknown file system-no mount point-128.00MiB-unused spaced-msftres Gparted print out (note dev/sda2 apparently that is normal behavior) : I went into Partition Magic/Gparted and confirmed : Boot menu has no UEFI/EFI (or Windows Boot Manager) entries anymore.Gave the 'reboot and select proper boot device' message Only SSD 1(Windows boot) and SSD 2 were listed in BIOS HDD 1 and HDD 2 were not visible.In short, I need to get the system/BIOS to allow UEFI booting of the SSD.Ĭomputer started up today with default BIOS settings.
